In the span of less than 12 hours last week, the Trump administration took two seemingly contradictory actions that could have profound effects on the insurance marketplaces set up by the ACA. First, officials issued guidance Monday morning that could weaken the exchanges set up for people who buy their own insurance. The new approach makes it easier for states to get around some ACA requirements. Yet, the other move could bolster ACA marketplaces by sending millions of people with job-based coverage there, armed with tax-free money from their employers to buy individual plans.
